Hands-on experience deploying to a cloud platform (Azure preferred) and using CI/CD tooling (Azure DevOps, GitHub Actions, or equivalent).
Solid understanding of software design patterns, SOLID principles, and secure coding practices.

Preferred QualificationsMicrosoft certifications (e.g., Azure Developer Associate, Azure Solutions Architect).
Experience with microservices, containerization (Docker, Kubernetes), and message-based architectures.
Familiarity with automated testing frameworks (xUnit, NUnit, MSTest) and test-driven development.
Exposure to low-code/no-code platforms (Power Platform, Salesforce, ServiceNow, Appian) or BI/analytics tools.
